DFU in Arduino Leonardo

Hello.

I need to program my leonardo with the .hex file however, I don’t know how to enable “DFU mode”. The FLIP software does not detect my arduino. What should I do? I don’t want to solder anything.

Thanks in advance.

Bump.

I think I’m not the only one here who cannot understand your question. What is this .hex file that cannot be uploaded using the normal methods (the Arduino IDE, avrdude)? Why do you need DFU mode on a device that has a single processor for every thing, including communications?

Yeah, my bad. DFU is not needed. Thanks for the reply
